Storage Onion, 'Rossa di Milano'

(Allium cepa) This has been our absolute favorite storage red for years. From Northern Italy comes this unusually shaped flat-topped onion with very attractive bronze-red skin. A first-rate OP storage onion that is medium-sized, very productive, and uniform. In a 2014 storage onion trial done by the Organic Seed Alliance, under heavy disease pressure, Rosa showed excellent horizontal resistance to downy mildew. It stores easily until spring, and it always tastes delicious! 110 days. Long day. TR

Growing Info

SOWING:

Sow indoors from late Feb-mid March, 6-8 weeks before your last frost. 

Transplant out 4-6 weeks before the last frost date (April-early May).

Note: Long-day onions are perfect for growing at higher latitudes, north of 35 degrees. 

PLANTING DEPTH:

1/4-1/2"

SPACING:

4" spacing in rows 15-24" apart.

EMERGENCE:

7-14 days @ soil temp 60-75F

LIGHT:

Full sun

FERTILITY:

Medium-Heavy. Prefers well-drained, loamy, well-balanced fertile soil with a pH between 6.0-7.0. 

ADDITIONAL NOTES:

Alliums would like you to keep them well-weeded as they are slow-growing and compete poorly.

Onion bulbing is sensitive to day-length. 

Shallow-rooted onions prefer even watering.

Harvest when the tops have fallen over. We sun-cure, placing the bulbs on screens and taking care to cover each one with the next onions leaves.
